to be honest your contridicting yourself.
its sasukes technique. his eyes (itachi eyes), therefore sasuke is ammune to infinate tsukiyomi
until his eyes need to recharge which i estimate to be not any time soon.
sasuke can see limbo. hence him being ammune to rinnegan techs.
sasuke can use his eye to create a shield out of susanoo
the only reason sasuke flew down to the grownd was to protect , kakashi,naruto and sakura. thats all he could have stared directly at the moon with no affect his eye is at the same level as madaras forhead eye
